Abstract
A tap and chaser are provided each having a cylindrical tool receiver connected to a threading section by a shaft. The receiver and shaft are of diameters sufficiently small to enter the bore hole and distribute any off axis load onto a number of internal threads of the bore hole to dissipate loading. The threaded section includes a group of longitudinal flutes. Each of the lands of the threaded section includes a novel cutting face, tooth angle and rake angle to advantageously allow for threading deep blind holes.

A tap comprising:
- a receiver, with a first diameter, having a drive socket, a longitudinal axis and a radial axis;
- a shaft section, with a second diameter, connected to the receiver, coaxial with the longitudinal axis;
- a threading section, connected to the shaft section, coaxial with the longitudinal axis;
- the threading section further comprising a set of generally longitudinal flutes with each generally longitudinal flute of the set of generally longitudinal flutes, forming a helix angle with the radial axis;
- the threading section further comprising a set of threads having a crest diameter and a root diameter;
- wherein the root diameter is greater than the first diameter and the second diameter;
- and
- wherein the receiver has a first length, the shaft section has a second length and the threading section has a third length;
